IMPEDANCE

Switch

This

switch

determines

the

input

impedance

of

the

INPUT

R

and

UMONO

jacks,

and

the

front

-panel

INPUT

jack.

When

directly

connecting

a

guitar

or

other

high

-

impedance

instrument

to

the

FX900,

set

this

switch

to

the

"1M"

position.

The

"10k"

setting

is

appropriate

for

standard

audio

equipment

and

other

line

-level

sources.

73

Input

Level

—20dB/+4dB

Switch

This

switch

allows

the

input

sensitivity

of

the

FX900

to

matched

to

the

type

of

source

equipment

used.

When

connecting

the

FX900

to

professional

equipment

that

has

+4

dB

outputs,

set

the

input

level

switch

to

the

"+4dB"

position.

The

"-20dB"

setting

is

the

best

choice

for

most

home

-use

audio

equipment.

0

INPUT

R

&

UMONO

Jacks

The

INPUT

R

and

UMONO

jacks

allow

either

stereo

or

mono

signals

to

be

fed

to

the

FX900.

Stereo

signals

should

be

fed

to

both

jacks,

while

a

mono

signal

should

be

fed

to

the

UMONO

jack

only.

Inserting

a

plug

into

the

UMONO

jack

only

causes

the

FX900

to

function

as

a

1-

in/2-out

type

signal

processor.

The

UMONO

jack

duplicates

the

function

of

the

front

-panel

INPUT

jack

described

in

the

following

section.

If

plugs

are

inserted

into

both

the

front

and

rear-panel

inputs,

the

front

-panel

input

jack

takes

priority.

0

OUTPUT

R

and

OUTPUT

L

Jacks

These

are

the

main

stereo

outputs

from

the

FX900.

We

recommend

using

both

outputs

and

connecting

them

to

the

corresponding

right and

left

channels

of

a

stereo

sound

system,

since

the

full

impact

of

many

of

the

FX900

effects

can

only

be

appreciated

in

stereo.

If,

however,

only

a

mono

sound

system

is

available,

use

either

the

OUTPUT

R

or

OUTPUT

L

jack.

0

Output

Level

—20dB/+4dB

Switch

This

switch

is

used

to

match

the

output

level

of

the

FX900

to

the

input

sensitivity

of

the

amplifier,

mixing

console

or

other

device

it

is

feeding.

For

compatibility

with

standard

line

-level

inputs

the

"-20dB"

setting

should

be

appropriate,

while

the

"+4dB"

setting

should

be

used

when

the

FX900

is

connected

to

professional

equipment

that

has

+4dB

inputs.

®

MIDI

IN

Connector

The

MIDI

IN

connector

accepts

MIDI

signals

from

an

external

MIDI

device

such

as

a

MIDI

foot

controller,

keyboard,

etc.

The

FX900

will

accept

MIDI

PROGRAM

CHANGE

messages

to

directly

select

effect

programs,

or

MIDI

CONTROL

CHANGE

messages

via

which

individual

effect

parameters

may

be

remotely

controlled.

MIDI

THRU/OUT

Switch

Selects

either

MIDI

THRU

or

MIDI

OUT

operation

for

the

MIDI

THRU/OUT

connector,

described

below.

®

MIDI

THRU/OUT

Connector

When

the

MIDI

THRU/OUT

switch

is

set

to

"THRU,"

MIDI

signals

received

at

the

MIDI

IN

connector

are

re-

transmitted

via

this

connector

in

real

time,

allowing

other

MIDI

devices

to

be

"chained"

to

the

FX900.

When

the

MIDI

THRU/OUT

switch

is

set

to

"OUT,"

MIDI

data

corresponding

to

operation

of

the

FX900

is

transmitted

via

this

connector.
